In the past several months, I called it quite intensive. I need to master the knowledge of FHIR, advanced dotnet technologies (attributes, generator, reflection, code emit, expression tree, advanced linq, customized aspnet pipeline, nuget package), code optimization technologies and several aws technologies (DynamoDB, S3, glue, spark) in depth to meet the schedule of a project. You really can’t account on solution architects or support engineers from cloud providers. I don’t get one perfect answers from them so far when I used their services.
